TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, CHARLES E. STEARNS, of Boston,'in the county of Suffolk, and State of Massachusetts, have invented a new and useful Stair-Carpet Fastening, and do hereby declare the same to be fully described in the following specication, and represented in the accompanying drawings, of which- Fgure l is a front elevation, and

Figures 2 and 3 end elevations of it as applied to a carpet and stairs.

In such drawings, A denotes the carpet, and B B B the steps of the stairs. The purpose of the invention is to hold the carpet to the stairs at the angles of junctioin of each tread with the riser thereof. To this end a staple or eye, a, and a hook, `b, are inserted in each riser, or arranged therein at opposite edges ofthe carpet and close to the tread. A bar, C, having a greater diameter at its middle than at its ends, and having studs c c projecting from such ends, is employed, in connection with the hook and eye, as the fastening for holding the carpet in pla-'ce at the vertex of the angle of each tread and riser. The studs of the bar are inserted in the eye and hook, and with the har running across the carpet. The bar tapers from its middle each way, and in consequence thereof it will act as a spring to hold itself in connection with the eye and hook; and as it'has a shoulder, e, at each extremity, such bar cannot be slid endwie through either the hook or the eye, bnt in order to dis-engage it therefrom it must first be liftedvout of the eye.

The common stair-rod, made of round wire inserted in two eyes, is very liable to work out of place, and has to be inserted 'in the eyes or'withdrawn therefrom by being moved `endwise with reference to them. My carpet fastening-bar cannot easily get out of its eye and hook, for the shoulders will prevent any endwise movementof it,and,-'hesides, the spring of the bar will operate to hold it in placein the hook and eye.

I therefore do not claim 'thefcommon cylindrical stair-rodand its eyes as a carpet-fastener; but what I claim as my invention, is-

The combination and arrangement, of the hook and eye and the double tapering spring-bar, provided with shoulders and studs, as set forth.

C. E. STEARNS'.
